Explorer Problem

Explorer Problem, I have a Dell Vostro running XP pro with 5 separate accounts on it.
The problem is that when I Log On to my account and use explorer I’m bombarded with popups, but when I log on as some one else and use their Explorer on their desk top there’s no problems. I’m guessing I’ve downloaded something that’s latching onto my account only. I’m running MacAfee and Google popup blocker but they have no effect.
I’ve thought of creating a new account for my self and using that which does solve the problem but then I can’t easily access my email and as I’m the admin causes other probs as well.
Is there some way of copying the explorer settings from one account to another account.
